Abstract
A female terminal fitting ( 20 ) has an approximately tubular connection portion ( 22 ) with an open front end for receiving a tab ( 14 ) of a male terminal fitting ( 10 ). Concavities ( 30 ) extend longitudinally in the connection portion ( 22 ) at positions opposed to side surfaces of the tab ( 14 ). The concavities ( 30 ) enable the outside width (W) of the connection portion ( 22 ) to be small while securing a large clearance (C) outward from the side surfaces of the tab ( 14 ). The concavities ( 30 ) do not significantly decrease the strength of the entire connection portion ( 22 ). Additionally, the large clearance (C) avoids the need for highly accurate manufacturing.

Embodiment
Shown in Fig. 1-8A, metal joint of the present invention has male side terminal fitting 10 and female terminal fitting 20.Male side terminal fitting 10 is that the sheet metal that will have high conductivity carries out pressure processing and forms.As illustrated in fig. 1 and 2, male side terminal fitting 10 has opposite front-end and back-end and the main body between the two ends 11.Cylindrical part 12 is arranged in the back of main body 11, and is configured to be crimped onto the end of electric wire 40.Plug 14 is arranged in the front of main body 11, and its size is suitable for being connected with female terminal fitting 20.
As shown in Figure 2, plug 14 is formed by substrate 15, and it is the double-decker of A that half of the left and right sides of substrate 15 is folded to form width.The front end of plug 14 is that taper is directed in the female terminal fitting 20 with the more rear portion with plug 14.
Female terminal fitting 20 forms structure shown in Fig. 3 to 5 by the sheet metal with high conductivity being carried out pressure processing.Female terminal fitting 10 has opposite front-end and back-end.Cylindrical part 21 is formed on the rear end and is configured to be crimped onto the end of electric wire 40.Coupling part 22 is arranged in the front of cylindrical part 21 and is configured to receive the plug 14 of the male side terminal fitting 10 of coupling.
Coupling part 22 is roughly box-like, has therefore limited the general rectangular pipe that has open front and rear end.The general rectangular pipe of coupling part 22 has top board 23, the base plate 24 relative with top board 23 and relative left side and the right plate 25 that extends between top board 23 and base plate 24.Coupling part 22 is shorter relatively on the Width of female terminal fitting 20, and longer on its longitudinal direction.More particularly, coupling part 22 is slightly longer than the plug 14 of male side terminal fitting 10, and slightly wideer than the width A of plug 14.
Each recess 30 has the height of the thickness of measuring that is slightly larger than plug 14 between top board 23 and base plate 24.As shown in Figure 5, the depth H of recess 30 be side plate 25 thickness T about 20% to 50% between, preferably about 40% of side plate 25 thickness T.For example, the thickness T of side plate 25 can be about 0.25mm, and the depth H of recess 30 then is about 0.1mm.Recess does not make the outer surface distortion of side plate 25.Therefore, the outer surface of side plate 25 keeps straight and plane substantially.
Each recess 30 has limited from two clearance C that the side is outside of the plug 14 that inserts coupling part 22, shown in Fig. 8 A with the isolated part of conical surface.
Sun and female terminal fitting 10 and 20 are crimped onto the end of electric wire 40 and rubber stopper 41.Male side terminal fitting 10 inserts in the cavity 52 of positive housing 50 subsequently, makes plug 14 give prominence to the cover cap 51 that enters into positive housing 50 forward, as shown in Figure 6.Female terminal fitting 20 also is contained in the cavity 61 of cloudy housing 60 similarly.
The operation that positive housing 50 is assemblied in the cloudy housing 60 is carried out from state shown in Figure 6.More particularly, the plug 14 of male side terminal fitting 10 moves in the opening at front end place of corresponding coupling part 22 of female terminal fitting 20.Each plug 14 is subsequently in the space between shift-in elastic contact chip 27 and the protuberance 28, and makes elastic contact chip 27 strains.Sun housing and cloudy housing 50 and 60 lock together in predetermined insertion position, as shown in Figure 7.In this position, because the elastic-restoring force of elastic contact chip 27, each plug 14 flexibly is clipped between the summit 27A and protuberance 28 of corresponding elastic contact chip 27.Therefore, between plug 14 and coupling part 22, formed electrical connection, be electrically connected thereby corresponding sun and female terminal fitting are formed 10 and 20.
Clearance C between the respective side panels 25 of the side of plug 14 and coupling part 22 can allow plug 14 steadily also insert reliably in the coupling part 22.
Obtain predetermined clearance C between the side of plugs 14 and the female terminal fitting 20 by the recess on the inner surface that is formed on left side plate 25 30, shown in Fig. 8 A.
In the Comparative Examples shown in Fig. 8 B, the inner surface thickness of the side plate 2 of coupling part 1 is even, and identical with the thickness of 22 other positions, coupling part, and the inner surface of side plate 2 is flat.In this structure, plug 3 inserts in the coupling parts 1, and also have with Fig. 2 in the identical width A of width A of plug 14.Finally, if place, 1 side forms same clearance C in the coupling part, coupling part 1 opposite outer surface also just limits width w.
Differently, recess 30 is formed on the inner surface of left side plate 25.Therefore, the width W on coupling part 22 between the outer surface of all position epipleurals 25 less than Comparative Examples in the width w of coupling part 1, the amount that is differed from is the twice of each recess 30 depth H, shown in following formula:
W=w-(depth H * 2)
Therefore, the width W of coupling part 22 is diminished, also obtain from the outside big clearance C in 14 two sides of plug.
30 of recesses are formed in the zone relative with the left and right side of plug 14 in the left side plate 25 of coupling part 22.Therefore, the intensity of entire connection portion 22 has only reduction very in a small amount.
Between the side plate 25 of plug 14 and coupling part 22, obtained big clearance C.As a result, make sun and female terminal fitting 10 and no longer needed high-precision dimensional tolerance at 20 o'clock, so just can not reduce productivity ratio.
Therefore female terminal fitting 20 can make compact conformation and do not reduce its intensity and make productivity ratio.
Recess 30 forms by the inner surface of punching out side plate 25.Thereby female terminal fitting 20 can form in a series of pressure forming processes that are used for making female terminal fitting 20.Therefore the method that forms recess 30 has been guaranteed high productivity ratio.
Described with reference to the accompanying drawings specific embodiment above the present invention is not limited in.For example, the following examples are also included within the technical scope of the present invention.Do not deviate from marrow of the present invention and scope and can also carry out other change.
Each concave depth can form the only about half of of respective side panels thickness.Yet the permission degree of depth of each recess depends on the thickness of respective side panels.
Recess can only be formed on in the left side plate one.This structure is also included within the technical scope of the present invention.
The present invention also is applicable to the female terminal fitting that uses in the non-watertight connector.
Thereby the male side terminal fitting of coupling can be installed on the connector and directly be connected on the equipment part.More particularly, the present invention is widely used in such female terminal fitting: it has approximate box-like coupling part, to be connected with the plug of the male side terminal fitting of the coupling of inserting the coupling part from the front of female terminal fitting.
